Impact Murphy has been on the shelf since May 5 with a left knee injury that was categorized as between a Grade 1 and Grade 2 sprain. The backstop hasn't recovered from the injury as quickly as anticipated, but he seems to be responding better after visiting Dr. Neal ElAttrache in Los Angeles in late July and receiving a platelet-rich plasma injection for the knee. The Giants likely won't be able to pinpoint a more precise target date for Murphy's return until he's cleared to begin a minor-league rehab assignment.
